Projects

My software products and selected client work.

A mix of my own products and selected client sites. Most of my client work is around SQL Server, but I also build software products and take on occasional web projects.

Things I am building

Product work where I shape the logic, data model, decision flow, and long-term system direction directly.

Passary

A local-first password manager built around data ownership, isolation, and zero-knowledge operation.

No accounts / no tracking

Argon2id + AES-256-GCM

The starting point here was simple: passwords should not live in a cloud vault by default. They should stay with the user, locally, encrypted. The security model is built around Argon2id + AES-256-GCM, with a zero-knowledge approach and as small an attack surface as possible. Right now the focus is continued product work: browser extension, mobile direction, and later self-hosted or sharing use cases.

macOS menu bar utility

ResoSwitch

A native macOS menu bar app for switching display resolutions, HiDPI modes, and external monitor layouts without opening System Settings.

The problem is small but annoying: macOS can change display modes, but the control is buried when you need it often. ResoSwitch puts the useful choices in the top-right menu bar, with per-display favorites, Cmd+number shortcuts, and a safety prompt for unusual modes. The current public release ships as a PKG or DMG for macOS 13 and newer. It is still unsigned and not notarized, so installation is not yet as smooth as a polished Mac app should be.
